Bladekind is the primary Strife Specibus of both Dave and Dirk. Interestingly, Dave's specibus was already set to bladekind before the Ninja Sword was placed in his Strife Deck. When he fought his Bro his Ninja Sword was cut in half and became ½bladekind, changing how Dave fights throughout Sburb. He later is able to switch between bladekind and ½bladekind with help from his Timetables.

Bladekind's offshoot, ½bladekind, is possibly a reference to Aragorn (a.k.a. "Strider") from the The Lord of the Rings franchise. In the first book, The Fellowship of the Ring, Aragorn was shown to have a blade that was "indeed broken a foot below the hilt." (p.184) The fact that Dave Strider is the only one to use the ½bladekind specibus only puts emphasis on that possible reference. Andrew Hussie has made references to the series in the past, so it's not unthinkable that this could an earlier, more subtle attempt.

In a Strife between Dave and his Bro, the Ninja Sword is broken in half, creating the ½bladekind that Dave now has to work around. Dave is unable to change his Strife Specibus back because at the time he has no means to repair the blade.

This Unbreakable Katana was in the possession of Dave's Bro at the beginning of the comic. Bro uses it in the fight with Dave and Lil Cal. He also uses it to split the meteor that was supposed to strike Dave's apartment. After he fights Jack Noir in the Land of Heat and Clockwork, the sword stays stuck in the Beat Mesa, much like the sword in the stone. Jack discovers that the sword had some strange golden energy flowing through it, perhaps from the cracked Beat Mesa, and decides to take it with him. He later returns it to Bro in what appears to be an attempt to finish their duel from before. The two fight once again, and, when Jack gets prototyped a fourth time, he impales Bro upon his own sword, once again stuck vertically into the ground. Dave eventually comes upon Bro and his sword, and decides to try to break it horizontally, much to the dismay of Terezi. He fails and promptly makes a pirouette off the handle. Though Bro's body is eventually removed by Jade to be buried, the sword remains stuck in the cliff on LOWAS for the years of the journey to the new session. Later, when John and Roxy Lalonde return to LOWAS (now displaced from canon), Roxy, upon seeing the sword and hearing of Bro's funeral, sees it as a symbol for all the loved ones she has lost. She uses her Void powers to phase the sword out of the ground, and uses it as a grave marker, for the burial of the Rose that died after the events of [S] GAME OVER, and, symbolically, for all those that had died during the battle with the Condesce. When Rose's body is later taken from the grave by Jaspersprite, Roxy takes the sword back, planning to use it in the upcoming fight with the Condesce. The sword is in fact used for that purpose in [S] Collide, with Roxy backstabbing the Condesce in a decisive blow.

Post-scratch, another iteration of the sword is seen in the possession of Dirk Strider. The Brobot seems to own one as well, which it used in its Strife with Jake. It is apparently very sharp, capable of cutting through drones, which are ostensibly made of metal. While the other post-scratch kids all alchemized better (or at least different) weapons for themselves once in the Medium, Dirk was shown to still use the original katana, perhaps indicating its reliability. The sword is shown to materialize along with the Brain Ghost Dirk splinter that is manifested by Jake's mind. This version of the sword somehow remained after its owner dematerialized, and was thus able to be used to kill both Jake and Jane.

Given its relatively bland appearance, it is surprisingly one of the seven legendary weapons of cherubim folklore, and was originally forged by a Japanese master over the heat of a roaring manga fire and cooled in an enchanted spring where virgin horses bathe.

Being that its appearance in the comic is based on an actual image, it is arguably a SW-362, a generic "ninja sword", which is ironically very low priced and anything but unbreakable. Also, despite being called the Unbreakable Katana, it is broken on at least one occasion, during the final battle with B2 Jack Noir and Lord Jack. As of now, Caledfwlch is the only known thing able to break it.

(Cal-ed-Vool-ch, with a Welsh "ch", meaning Excalibur) A weapon capable of harming LrdEnglish. This sword is first found on Dave's planet, and was later alchemized by Jade while under the Condesce's influence, who found out it was her master's weakness during her centuries of servitude. Dave was unnerved to discover that his ultimate sword was just a repaired downgrade of my previously ultimate sword mixed with a cueball. The "caled" part of the name, as well as in "Caledscratch", means "tempered", while "fwlch" is a mutation of "bwlch", meaning breach or cleft.

Caledfwlch also appeared as a weapon in one of Homestuck composer Toby Fox's other works, the Earthbound Halloween Hack, as a weapon that "glows with the light of the sun". This sword might be able to cut through anything, as shown in Collide when Dave cuts the Unbreakable Katana (which is supposedly unbreakable due to its name).

It is implied that the magic cue ball, one of its alchemization components, is made of (or from the same material as) Caliborn's god tier clock; this sword might be able to kill any player who has also bypassed their conditional immortality rules.

Also known as the Legendary Piece of Shit, this sword is first found intact and stuck inside a golden stone inside a building on Dave's planet. Dave tries to retrieve it, but instead decides to break the sword in half by dropping a pillar onto it. It is an alchemization component of Caledscratch.

Davesprite mentions that the only way to get it out in the first place was to break it, as he did himself in the alternate timeline. He also says that John may have been capable of taking the sword out of the stone without breaking it due to his "pure heart," although it's hard to tell how serious he was being, especially since John was obviously not intended to do so. In Davesprite's timeline, the sword was stolen by one of Hephaestus' minions.

The sword itself is apparently very important to Hephaestus, Dave's Denizen, who wants access to the Kids' Forge, which he needs to repair the sword.

The Caledscratch is the version of the sword alchemized by Davesprite. This very powerful sword seems to bear some relation to Dave's Timetables, indicating that they may comprise one of the components of its Alchemization, along with the Broken Caledfwlch.

According to Andrew, the name is based on the Welsh name of Excalibur, Caledfwlch, the sword owned by King Arthur. Its name also has "Cal" in it, referencing Bro's little man Lil Cal. Along with "Excalibur", "Caliburn" also serves as an alternate translation to "Caledfwlch," which is very close in namesake to Caliborn. "Scratch" is a reference to the "scratch" performed when using a turn table. Caledscratch is also a reference to Doc Scratch, who was cloned from Lil Cal.

The Snoop Dogg Snow Cone Machete is the result of alchemizing Caledscratch, the mini A/C unit, and a photo of Snoop Dogg. It apparently has a blizzizzle nozzle that is to be turned up when foes drop it like it's hot, which will cause them to chizzlax fo' rizzle. Part of it is a Snoopy Sno Cone Machine.

The weapon is seen to freeze opponents before they are sliced in half. This sword is not ½bladekind, but Dave simply uses the bladekind abstratus in his strife portfolio to wield it.

The Deringer is a weapon created by Hephaestus using the Broken Caledfwlch and his Forge. At some point after his loss to Jack Noir, before the end of the Reckoning, Davesprite took the Broken Caledfwlch from Dave and went to see Hephaestus, who offered him The Choice. Davesprite chooses to have the sword repaired, so Hephaestus uses the Forge to create the Royal Deringer. Davesprite ultimately travels to the Battlefield with this sword, where Jadesprite uses her powers to teleport it to Rose and Dave, where it appears, embedded into the base of Derse's moon-binding chain. In his attempt to retrieve it, Dave breaks it, turning it into the Broken Royal Deringer.

The name is a reference to the Derringer, a type of muzzleloading pistol (and itself a misspelling of the last name of gunmaker Henry Deringer) and a pun on 'de-ringer', a reference to how Narsil was used to remove the One Ring from Sauron's hand (along with several of Sauron's fingers); mirroring this, the broken Royal Deringer is also used by Jack Noir in [S] Jack: Ascend. to deprive the Black Queen of her ring, killing her and opening the way for Noir to usurp the throne.

Dave broke the Royal Deringer, changing it to ½bladekind form, when he tried to retrieve it from the base of the chain anchoring Derse's moon, which he then used to sever this chain.

This sword is one of the weapons held by Liv Tyler. In the B2 session, Jake retrieved this sword, as well as the other weapons, from the Lotus Time Capsule on his island. He then sent them and the bunny to Jade, who gave the whole package to John for his birthday. Jack Noir used this sword to cut the ring off his Black Queen's finger.

The sord..... is created by alchemizing one of Bro's shitty swords with a picture of Hella Jeff. The shitty sword from which it was made, and thus the sord..... itself, bear a striking resemblance to the Caladbolg from Final Fantasy X, which follows the pattern of Dave having "Cal" swords.

This thing is so unspeakably shitty it costs zero Build Grist and even Dave has a hard time holding it.

It is later seen in the corner of Dirk Strider's Room. Dirk's Bro made a shit ton of money from it (and other jpeg crap no-one wants) because it actually costs negative amounts of money to make.

This sword is used by Vriska when she achieves "Ancestral Awakening" with her Fluourite Octet dice. It's possible it belonged to Marquise Spinneret Mindfang during her lifetime. It glows with a powerful blue aura when wielded by Vriska. Notice how the blade and crossguard resemble Vriska's horns. It's unclear whether or not Vriska requires a Bladekind Specibus to wield it or if she can wield it because it was generated by her Fluourite Octet.

Dave tries to alchemize the Scarlet Ribbitar by combining the Caledscratch with Ruby Contraband. He cannot create it is due to its extremely high cost, which includes 2,000,000 of a type of grist he has not yet encountered. The name is a play on "scimitar", a sword with a curved blade.

Dave is seen wielding the sword against Jack at a later point in the three days he's so far spent in the last day before the Scratch, presumably having advanced enough to afford it.

Meenah Peixes later finds it in a dream bubble, and being made of ruby, it is safe to assume that she kept or sold it. This implies that Dave may have switched it for a more powerful or less ridiculous weapon.

Dave also attempts to alchemize a Broken Scarlet Ribbitar, which is still too expensive. It may have time powers like the Broken Caledscratch that allow Dave to transform it back into a full blade. This is implied due to the small break the full sword has where the broken Scarlet Ribbitar ends. It costs half as much grist as the unbroken Scarlet Ribbitar.

Jack Noir states that he makes a policy of handing out a Regisword and a hit list with two crownsillouettes to just about anyone who enters his office, so clearly they are very common on Derse.

The name is a combination of the root 'Regis,' Latin for 'of the King,' and 'Sword.' It is also a pun on the word "regicide," meaning the murder of royalty, since it was intended to be used to slay the White King and Queen. It may also be a pun on "registration" as Jack gives it to the Parcel Mistress along with the cards as signs that she's chosen to perform the task of 'slaying' the White King and Queen and there may be no turning back.

Karkatwields a sickle that resembles a Regisword, suggesting he alchemized one with a sickle. This makes sense, as he could have obtained it from their Jack Noir.

The Cutlass of Zillywair is one of the legendary weapons of cherubim folklore, representing its namesake continent. Apparently it was swashed from the buckles of the rough'n tumble Bellyjape Seamen and offered atop the kingdom's last known wildly occurring pluffy dimplepillow to the resplendent 1st Rumbylumplewiffig of the Horsehorsehorse Administration.

This sword is forged together by Alpha Male using pictures Dirk drew for Caliborn. Whether these images can actually be considered pornography is debatable. Alpha Male uses this lewd weapon to slay a witch, unfortunately a horse also dies in the process. The sword is a reference to a Paper Sword created by the main character of Jailbreak as well as the similar knife which Jack Noir forged out of illicit material during his own jailbreak adventure.

Due to Dave's' prototyping, several versions of his ninja sword, made of varying material (including sprite and carpacian) and size exist throughout the medium, appearing within the chests of creatures affected by the prototypings of the B1 session.
